Additional resources I will have extended office hrs. Mayer 4517. Thu Fri Mon 2-4 pm. You can ask me questions by email [email protected] The clicker question will be placed online. Preparing for the final exam • Review previous quizzes. Find what you did wrong and learn to correct your errors. • Go over homework and clicker questions. Make sure you understand the basic ideas not only the numerical solutions. Ch. 13 Harmonic Oscillations Know the relations between displacement and time for simple harmonic motion. . Harmonic oscillators Displacement y=Acos( ω t) Know how the frequency depends on properties of the system. Mass on a spring Pendulum f 2 π = ω k m ω = L g = ω 1 f T = Chapter 14 Waves Longitudinal Waves Transverse Waves Know the relation between wavelength, frequency, period, speed Transverse wave on a string. Know how to calculate the velocity. Power - proportional to the square of the amplitude. Intensity =power/area Superposition principle.
